compound eye

Array of contiguous ommatidia having common optic nerve trunk; paired [Moore and McCormick, 1969].

Paired array of contiguous ommatidia having common optic nerve trunks [McLaughlin, 1980].

(Order Cladocera):

One of two large photosensitive organs on head; sessile, typically fused, and enclosed within optic vesicle. Movable by series of optic muscles. Relative position of compound eye on head (e.g., anterior, in middle near ventral margin) may be of taxonomic importance [Stachowitsch, 1992].

(Order Notostraca):

One of two larger photosensitive organs located on sloping anterior part of carapace; sessile. (See also eye tubercle, nauplius eye). (Syn. lateral eye) [Stachowitsch, 1992].

(Order Diplostraca):

One of two large photosensitive organs located on anterior end of head; sessile, either closely adjoining or partially fused. Enclosed almost entirely within optic vesicle [Stachowitsch, 1992].

(Order Anostraca):

One of two relativel large, stalked photosensitive organs projecting from each side of head. (See also nauplius eye) [Stachowitsch, 1992].

(Order Leptostraca):

Eye [Stachowitsch, 1992].

(Subclass Branchiura):

One of two organs of vision suspended in a blood sinus on dorsal surface of carapace; each movable eye consists of numerous ommatidia, yet lacks true outer cornea [Stachowitsch, 1992].

(Subclass Cirripedia):

Cypris larva [Stachowitsch, 1992].

(Class Ostracoda):

One of two more complex anterodorsal organs of vision. Each is contained in ocular sinus beneath eye tubercle. (See also nauplius eye) [Stachowitsch, 1992].

(Order Euphausiacea):

Pair of larger organs of vision, each located distally on eyestalk (ocular peduncle), (divided = bilobed = multilobed, undivided = single-lobed = spherical, imperfect) [Stachowitsch, 1992].
